Curved display panel, manufacturing method thereof and display device

Abstract

The invention provides a curved display panel, a manufacturing method thereof, and a display device. The manufacturing method of a curved display panel provided by the present invention comprises steps of: preparing a support plate, which comprises a first base and a metal film deposited on one side of the first base, the thermal expansion coefficient of the first base being different from that of the metal film; bonding a display panel with the support plate; heating the support plate, so that the support plate forces the display panel to bend; and separating the support plate from the display panel, thus forming the curved display panel. The manufacturing method of a curved display panel of the present invention is simple in process and not prone to causing damage to the panel.

The invention claimed is: 
     
       1. A manufacturing method of a curved display panel, comprising steps of:
 preparing a support plate, which comprises a first base and a metal film deposited on one side of the first base, the thermal expansion coefficient of the first base being different from that of the metal film; 
 bonding a display panel with the support plate; 
 heating the support plate, so that the support plate forces the display panel to bend; and 
 separating the support plate from the display panel to form the curved display panel. 
 
     
     
       2. The manufacturing method of  claim 1 , wherein the step of bonding a display panel with the support plate comprises:
 coating a side, without the metal film deposited, of the first base with glue, and bonding the display panel with the first base through the glue. 
 
     
     
       3. The manufacturing method of  claim 2 , wherein the glue is a liquid transparent optical adhesive. 
     
     
       4. The manufacturing method of  claim 2 , wherein before the step of coating a side, without the metal film deposited, of the first base with glue, the step of bonding a display panel with the support plate further comprises:
 cleaning the first base and the display panel. 
 
     
     
       5. The manufacturing method of  claim 2 , wherein the metal film is made of aluminum. 
     
     
       6. The manufacturing method of  claim 1 , wherein the step of bonding a display panel with the support plate is executed in vacuum. 
     
     
       7. The manufacturing method of  claim 1 , wherein the display panel is a flexible display panel. 
     
     
       8. The manufacturing method of  claim 7 , wherein the flexible display panel comprises a substrate, which is a polymer substrate. 
     
     
       9. The manufacturing method of  claim 8 , wherein the flexible display panel further comprises a touch driving layer arranged on the polymer substrate and a protective layer arranged on the touch driving layer. 
     
     
       10. The manufacturing method of  claim 8 , wherein the polymer substrate is made of a thermosetting polymer material. 
     
     
       11. The manufacturing method of  claim 8 , wherein the polymer substrate is made of a thermoplastic polymer material. 
     
     
       12. The manufacturing method of  claim 1 , wherein the first base is a glass base. 
     
     
       13. The manufacturing method of  claim 1 , wherein the metal film is made of aluminum. 
     
     
       14. The manufacturing method of  claim 1 , wherein in the step of heating the support plate, the heating temperature is 150-250° C.
